Nasa announced plans today regarding our return to the moon. By 2020, Nasa would like a permanent base where future missions can be launched avoiding Earth's gravity. Besides all the cool space exploration that could go on from here, think about the tourism aspect. People would pay lots of money to stay on the moon and Nasa could use that money to fund other projects. My goal in life is to make it to space before I die and since Mars is not feasible, the moon will do. I will be in my late 40s/early 50s by the time we have a base but that won't be a problem, I will make sure I am in excellent shape.
